Why did my banana catch fire in the microwave?

Your banana caught fire in the microwave because it got really hot, too fast, like when you run outside on a cold day and your nose freezes instantly.

How Microwaves Work

Microwaves use waves to heat things up. These waves are invisible, but they work like sound waves, they vibrate inside the food, making the molecules move faster and get hotter. This is why your soup gets warm so quickly in the microwave.

Why the Banana Caught Fire

Bananas have a lot of water in them, which helps carry heat around. But when you put a banana in the microwave, especially if it's not peeled or cut up, the skin can act like a blanket, trapping all that heat inside. It’s like wearing a thick coat on a hot summer day.

If the microwave is powerful and the banana isn’t moving much, the heat builds up really fast. Soon enough, the banana gets so hot that it starts to burn, just like when you leave your toast in the toaster too long, poof, smoke and fire!
